Abstract: The present disclosure includes a high voltage electrical system that may include a power source, a power source control module that may be electrically connected to the power source, and a controller. The power source control module may include a switch and a converter. The converter may be disposed electrically in parallel with the switch. The controller may be configured to control operation of the switch and the converter. The controller may be configured to selectively electrically connect the power source with an electrical load via the switch and the converter.

Abstract: In at least one embodiment an apparatus for diagnosing electronics in an insulation resistance monitoring system is provided. The apparatus includes a controller for being electrically coupled to a plurality of electronics including a plurality of switches that are electrically coupled to a positive branch and to a negative branch in a high voltage network and a low voltage network. The plurality of electronics is configured to perform insulation resistance monitoring in a vehicle. The controller is further configured to at least one of activate and deactivate any number of the plurality of switches to determine an overall voltage of the positive branch and the negative branch. The controller is further configured to detect a fault in at least one of the positive branch and the negative branch that corresponds to a failure of any one of the plurality of electronics based on the overall voltage.
